Prokaryotic cells have various shapes; the four basic shapes are: Cocci - spherical Bacilli - rod shaped Spirochaete - spiral shaped Vibrio - comma shaped.
  Prokaryotic Cells are cells that have to have organelles that are not surrounded by a membrane and do have ribosomes. Their DNA is in the shape of a circle. They have no â¦ nucleus, the DNA is bunched up in the cytoplasm. Both Prokaryotic Cells and Eukaryotic Cells have an outer cell membrane.   But, prokaryotic cells do not have membranes around their organelles (inside the cell â¦), whereas eukaryotic cells do.
